AWS Storage Services | S3 (Simple Storage Services)

 

S3 (Simple Storage Services)

• S3 stand for simple storage services
• AWS S3 highly scalable, reliable, fast, inexpensive data storage service.
• S3 is Object-Level storage
• It is Object-based storage, i.e., you can store the images, word files, PDF, files, scrip, application files and DB data backup etc.
• AWS simple storage services is a storage services option offered by amazon
• It has unlimited storage so you can store the data as much you want.
• S3 is a pay as you go services
• Easily to define public and private rules in s3
• AWS S3 is object storage so it cannot be used for software installation and OS installation we will use to store object file like pdf, work, excel.
• Storage any amount of data, at any time, from anywhere on the web.
• Files size are stored in S3 can be from 0 Bytes to 5 TB
• Most of amazon’s static contents are stored on AWS S3.

 

S3 Bucket:

• A bucket is a container for object storage in Amazon S3, ever object is contained in a bucket.
• Buckets must have a unique name to generate a unique DNS address.
• Buckets are identifying the account responsible for storage and data transfer charges. Each bucket has an owner, and the account for the owner will be charged for the S3 storage costs. Access control rules can be applied to buckets.

Note: once you create your bucket, you can’t able to rename the bucket name and Region. Amazon S3 buckets are globally unique

 

S3 regions choosing:

• You might choose a region to optimize latency, minimize costs.
• Just think 90% of your clients are in Asia Pacific (Mumbai) Region. It's probably a good idea to choose a region in Asia Pacific (Mumbai) Region for your S3 bucket; you cannot create a bucket in North America and store Asia Pacific user's information there.
• Based on Website hosting and client access we can choose the best region for S3.

 

Use cases of S3

• One interesting use case is its ability to host static websites in Amazon S3, Static website in single page there is no storage increase so we can host in S3  
• It is Object-based storage, i.e., you can store the images, word files, pdf files, strip, application files and DB data backup etc. 
• Amazon S3 provides data backup and storage from other services such as EBS, snapshots and AMI templates, Cloud front. 

Note: we can host static website in amazon s3 because hosting cost too high for webserver, static website in single page there is no storage increase so we can host in amazon S3  

 

S3 Advantages:

Only use AWS S3 to store objects. Now let's take a look at the data consistency model for Amazon S3. Imagine you have a bucket and you upload a file to it. You are in the West US region. Imagine you have clients all over the world, so what they're going to see, are they going to immediately see the file you just uploaded? The answer is yes. Amazon AWS provides a strong read‑after‑write consistency for new objects. This means as soon as you upload your new objects to Amazon S3, all the clients around the world are going to see this new object and download it. The same is true for UPDATES and DELETES. Now, Amazon S3 provides strong read‑after‑write consistency for PUT updates and also DELETES. This means as soon as you go ahead and update a file or delete a file, your clients around the world will see this new update. Previously, this was not the case because Amazon AWS was only providing eventual consistency. This meant that you could delete a file from your bucket and the client on the other side of the world could be able to download the deleted file for the next half a second or after that it’s not an available.

S3 different storage Classes:

• Standard
• Intelligent Tiering
• Standard Infrequent Access
• One Zone Infrequent Access
• Glacier
• Glacier Deep Archive

 

 

 

 

 

 

 

  

S3 different storage Classes:

• S3 Standard
• Intelligent Tiering
• Standard Infrequent Access
• One Zone Infrequent Access
• Glacier
• Glacier Deep Archive

S3 Standard (General purpose)

• S3 Standard offers high durability, availability, and performance object storage for frequently accessed data.
• S3 Standard delivers low latency and high throughput.
• Supports SSL for data in transit and encryption of data at rest.
• S3 standard is the most expensive storage compares all others.
• The data is stored in 3 availability Zone

S3 Standard use cases :

Cloud applications, dynamic websites, web services, websites hosting, big data analytics, mobile gaming, and content distribution

 

 

S3 Standard-IA ( Infrequent access)

• S3 Standard-IA is used to store data which is accessed less frequently but need quick access when needed.
• S3 Standard Infrequent access less expensive compare than standard storage but Amazon charges a retrieval fee to retrieve the data.
• S3 Standard-IA is High durability, Low latency and high throughput performance of S3 Standard but has a low per GB storage price and per GB retrieval price.
• The data is stored in 3 availability Zone
• Designed for 99.999999999% ( 11 9’s ) Durability of objects across AZs
• Designed for 99.9% availability over a given year.

The S3 Standard-IA use cases:

Backups, long-term storage, and as a data store for disaster recovery.

 

S3 Intelligent storage class (Unknown or changing access) 

 

• S3 Intelligent Tiering monitors your data access patterns and moves the data to different storage classes automatically.
• S3 Intelligent Tiering storage class is designed for optimize storage costs by automatically moving data to the most cost-effective storage access tier, without performance impact or operational overhead.
• Automatically moves the data between two access tiers. (Infrequent Access and Frequent Access)
• Objects that have not been accessed for 30 consecutive days to the infrequent access tier. If the object is accessed then it is automatically moved back to the frequent access tier
• There are no retrieval charges in S3 Intelligent-Tiering but small monthly monitoring and auto-tiering movement charge.
• The data is stored in 3 availability Zone
• Durability of 99.999999999% (9 9’s)
• Availability of 99.99% availability over a given year of objects across AZs.

Note: If an object in the Infrequent or Archive Instant Access tier is accessed later, it’s automatically moved back to the Frequent Access tier. If the object you’re retrieving is stored in the optional Deep Archive tiers, before you can retrieve the object, you must first restore a copy using RestoreObject.

 

 

 

S3 One Zone-Infrequent Access (S3 One Zone-IA)

• S3 One Zone-Infrequent Access storage classes are designed for long-lived and infrequently accessed data in one availability Zone.
• This is a low-cost storage option compared to S3 standard storage and Standard Infrequent access.
• S3 storage class store data in a minimum of 3 Availability Zones (AZ), S3 One Zone-IA Stores the object data in only one AZ, which makes it less expensive and the costs 20% lesser than the Standard-Infrequent Access
• Durability for 99.999999999% (11 9’s)
• Availability 99.5%

User Case:

• Store infrequently accessed non-critical data or data which can be regenerated if lost because this storage class stores the data only in one availability Zone.
• S3 One Zone-Infrequent Access cross-region replication
• S3 One Zone-IA is ideal for customers who want a lower-cost option for infrequently accessed data but do not require the availability
• It’s a good choice for storing secondary backup copies of on-premises data or easily re-creatable data 
• We can also use it as cost-effective storage for data that is replicated from another AWS Region using S3 Cross-Region Replication.  

 

 

Glacier (Archive Storage)

• Amazon Glacier is a perfect solution for long storage and archiving of data which don’t require frequent access
• Backup retrieval process may take minutes to hours
• Minimum Storage class duration period of 90 days 

 

Glacier Deep Archive

• S3 Glacier Deep Archive is Amazon S3’s lowest-cost storage class and supports long-term retention and digital preservation for data that may be accessed once or twice in a year.
• It is designed for customers particularly those in highly-regulated industries, such as the Financial Services, Healthcare, and Public Sectors , that retain data sets for 7–10 years or longer to meet regulatory compliance requirements.
• Minimum Storage class duration period of 90 days

Use cases:

S3 Glacier Deep Archive can also be used for backup and disaster recovery use cases, and is a cost-effective and easy-to-manage alternative to magnetic tape systems, whether they are on-premises libraries or off-premises services
